HAY-TEDDER.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application led November 18, 1908. Serial No. 463,219.

To all whom it may concern:

Be it known that I, JOHN F. HERMANN, a citizen of the United States,residing at Mo` line, in the county of Rock Island and State ofIllinois, have invented certain new and useful Improvements inHay-Tedders, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention comprises certain novel improvements in tedders wherebythe same may be readily attached to, and receive power from, a mower,and in which certain novel cooperating lever mechanism is employed tooperate the tedding forks.

In connection with the foregoing, the invention also contemplates theemployment of novel mechanism or raising or lowering the tedder frame soas to place kthe tedding forks in an operative or inoperative positionas desired.

In carrying out the objects of the invention generally stated above itwill of course be understood that the essential features are susceptibleof structural changes and modifications in details, but a preferred andpractical embodiment of the same is shown in the accompanying drawings,wherein- Figure l is a side elevation of the improved tedder, showingthe same coupled to the rear axle of a mower. Fig. 2 is a top plan view.Figs. 3 and 1 are detail views of the eccentrics shown in Fig. 2. Fig. 5is a detail view of the coupling for connecting the fork arms with theiroperating crank. Fig. 6 is a similar view of the coupling for connectingthe fork operating arms with their cranks.

Like characters of reference designate corresponding parts.

Referring to the accompanying drawings, 1 designates a rear axle of amower which has mounted thereon a sprocket wheel 2.

The impro-ved tedder comprises primarily a frame composed of side beams3 and connecting beams l, the side .beams 3 having end coupling members5 for detachably connecting them with the axle 1 of the mower. The otherends of said beams 3 carry shaft hangers 6 which support a transverselyextending shaft 7 upon each end of which a bracket 8 is held, saidbracket at its lower end being provided with a longitudinally extendingshaft recess 9 for the reception of a shaft, or pintle 10, the lowerportion of which is enlarged and divided to form outwardly curvedbifurcated members 11 formi ing ears for the reception of a shaft 12carrying a wheel or roller 13. Adjacent to the coupling ends of the sidebeams 3, an upright lever ll is mounted, said lever being provided witha hand operated pawl 15 which engages with a segment 16 mounted on saidbeam. The lower end of the lever 14 connects with a horizontallyextending rod 17 mounted in bearing blocks on said beam 3, said rod 17carrying a lever 18 which has a pivotal connection with one end of a rod19 the other end of which is connected with the upper end of the bracket8.

position beneath or beyond the frame of thev tedder, which movement ofthe said rollers will raise .or lower the end of said frame owing to thedescribed mounting of said rollers.

Each of the side beams 3 has mounted on its rear end portion an upwardlycurved standard 20 the lower or inner end of which has bearings formedthrough it for the reception of a shaft 21 carrying a sprocket wheel '22which has a sprocket chain connection 23 with the sprocket wheel 2mounted on the axle 1 of the mower. Said shaft 21 has eccentrics 24mounted thereon which carry loose castings 25 which receive one end ofarms 26 for imparting an outward and inward movement to the teddingforks, as will presently be explained. A pinion 27 is also mounted onsaid shaft 2l`with which a similar pinion 2S is held in mesh, saidpinion 28 being fast on one end of a shaft 29 the other end of which isalso provided with a pinion 30 that is held in mesh with a pinion 31fast on a crank shaft 32 which is mounted in bearings 33 formed in theupper end of the standard 20. Said crank shaft 32 is provided with aplurality of cranks 34C, corresponding in number to the eccentricsmounted on the shaft 21, said cranks being so arranged that theyalternately project in opposite directions, and each have a sleeve 35loose thereon and provided with outstanding spaced apart flanges 36forming a housing for the reception of one end of a fork rod or bar 37the free end of which carries a fork 38. Adjoining each crank 34, thesaid crank shaft carries a loose sleeve 39 which is provided With spacedapart flanges 40 which receive and hold the upper ends of fork operatingarms 41. The lower ends of said arms 41 have a pivotal connection with abracket 42 carried by the forks 38.

The intermediate portion of each forkoperating arm 41 has fast thereon abearing block 43 to which the outer end of each of the arms 2G carrie-dby the shaft 21 is pivotally connected.

t will be understood from the foregoing that a turning of the mower axle1 will impart a similar movement to the shaft 21, and through thedescribed pinion and shaft connection with the crank shaft 82, a similarmovement will be imparted to the latter. The turning of the shaft 21causes its eccentrically mounted arms 26 to be reciprocated and, throughthe connection between said arms 26 and the fork operating arms 41, thelatter will be rocked forwardly and rearwardly in alternation. Theturning of the shaft 82 causes the arms 41 and 37 to alternately raiseor lower, the raising or lowering of the arms 41 imparting a kickingmovement of the lower end of the arms 37 to cause the forks to throwthe. material gathered, in a manner well understood.

From the foregoing it will be seen that the described system ofcooperating rods or arms is one that assures of the desired movement ofthe fork arms in a positive and direct manner without any other powerthan that derived from a turning movement of the mower axle.

Another distinctive feature of the present invention is in the describedmanner of elevating or depressing the rear end of the tedder frame,which greatly facilitates the placing of the forks in a position wherethey will properly handle the material being gathered, or may be readilyremoved from such position.

Claims 1. A tedder comprising a frame, standards carried by one end ofsaid frame, a crank shaft mounted in the upper ends of said i'standards, tedding forks swiveled to the cranks of said crank shaft,fork operating arms swiveled to said crank shaft and having a pivotalconnection with said forks, and arms having a swiveled connection withsaid fork operating arms.

2. A tedder comprising a frame, standards carried by one end of saidframe, a shaft journaled in the lower end of said standards, eccentricsmounted on said shaft, arms connected to said eccentrlcs, a crank shaftjournaled in the upper ends of said standards, tedding arms mounted onthe cranks of said crank shaft and carrying forks at their free ends,fork -operating arms carried by said crank shaft and having their lowerends pivotally connected with said forks and their intermediate portionsconnected with the eccentrically mounted arms, and means for rotatingboth of said shafts to cause the eccentrically mounted arms to impart anoutward and inward movement to the fork operating arms, and an upwardand downward movement to said tedding arms and said fork operating armsin alternation.

3. A tedder comprising a frame, standards carried by one end of saidframe, a shaft carried by the lower end of said standards, armseccentrically connected with said shaft, a shaft carried by the upperend of said standard and provided with a plurality of cranks arranged inalternation, tedding arms loosely connected with said cranks, andprovided with forks at their free ends, fork operating arms looselyconnected with said shaft adjacent to each crank, a pivotal connectionbetween said forks and said fork operating arms, and a pivotalconnection between said eccentrically connected arms and said forkoperating arms.

4. A tedder comprising a frame, standards carried by one end of saidframe, a shaft journaled in the lower end of said standards, armseccentrically connected with said shaft, a shaft journaled in the upperend of said standards and provided with a plurality of crankscorresponding in number with the arms carried by the first mentionedshaft, fork arms having a loose connection with said cranks, forkscarried by said fork arms, fork operating arms loosely connected withsaid shaft adjacent to each crank, a pivotal connection between saidfork operating arms and th forks, and a pivotal connection between saidfork operating arms and the eccentrically mounted arms.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
